Frequently Asked Questions About Homoglyph Detector
What is a homoglyph?
A homoglyph is a character that looks like another character but has a different Unicode codepoint. For example, Cyrillic "а" (U+0430) looks identical to Latin "a" (U+0061) but is a different character.
Why should I detect homoglyphs?
Homoglyphs are often used in phishing attacks (lookalike domains) and can cause issues in text processing, search indexing, and content validation. Detecting them helps ensure text authenticity and security.
